AMS SENSIT 3 GLASS FRONT VENDOR
L0118E
1.0 INTRODUCTION
Congratulations on the purchase of your new AMS
Sensit 3 vendor. All Sensit 3 models, including Snack,
Visi-Combo, Bottle and Food Combo, Visi-Diner and
Milk, are versatile, high-capacity vending machines.
AMS machines are designed, tested, and built to
provide years of reliable, low-maintenance service in
an indoor environment. A fully insulated cabinet, DEX
data capability, and flexible product configuration are
just some of the many features built into every AMS
merchandiser.
1.1 SENSIT 3 SYSTEM
Your vendor is equipped with the Sensit 3
control system. The Sensit 3 system is a patented
vend-sensing system that detects when products fall
into the delivery bin. Basically, a plane of infra-red
light is created across the top of the delivery bin, and
the Sensit 3 system can detect when the light has
been blocked by a falling product. Using this
technology, the vendor “knows” when your customer
gets the product. The Sensit 3 system has several
important benefits:
Guaranteed Delivery
If, during the vend, the product hangs up or
an opening was missed in loading, the helix can
rotate several additional partial revolutions to attempt
to deliver the product. No more hitting or shaking the
vendor to get products that did not fall!
Instant Refund
If the customer does not receive a product,
he can receive a full refund by pressing the coin
return, or he can select another product. No more
refund requests!
Adjustable Helix Motion
With the Sensit 3 system, the helix can stop
as soon as the product falls, or when the helix returns
to the home position. See section 6.8 for more
information.
Additional Benefits:
1. Opening the delivery bin door will not affect the
Sensit 3 system. The sensors are located above
the delivery bin and will not be blocked by the bin
door. Product that falls while the door is open will
still pass through the beam.
2. Shining a light at a sensor will not allow vandals to
receive free product. Any tampering which
changes the precise amount of light normally
received will be treated as a successful vend,
resulting in the vandal losing his money.
3. Disabling or blocking the sensor will not allow
vandals to receive free product. The Sensit 3
system can over-ride blocked or malfunctioning
sensors and still vend.
1-1
4. Opening the door of a cold vendor will cause some
condensation to form inside. The Sensit 3 system
will not allow vending until this fogging clears,
normally within a few minutes of closing the door.
1.2 HEALTH AND SAFETY
H&S Specifications
AMS vendors intended for vending
perishable products (VISI-DINER, BOTTLE and
FOOD COMBO, and MILK) meet the National
Automatic Merchandising Association (NAMA)
requirements for refrigerated food vending machines.
As of this writing, the NAMA specifications for
perishable food product vendors require that the
temperature in the vendor must cool to 41°F within30
minutes of closing the door or a HS2 error will be
generated and the vendor will not allow sales of
protected items. (Note that Delayed Sales has no
effect on this 30 minute cool-down period). This is to
allow a recovery period following loading: however, all
products should be chilled prior to loading. After the
30 minute cool-down requirement has been met, if the
temperature in the vendor exceeds 41°F for more
than 15 minutes a HS1 error will be generated and
the vendor will not allow sales of protected items.
Selections that are ‘exempt’ from Health & Safety
protection will still be available. See section 6.6
H&S Software
To meet these requirements, all AMS
refrigerated food vendors have control software with a
built-in Health & Safety (H&S) function. The H&S
function is activated automatically in food vendors
when the temperature is set to 41°F or below. Unless
otherwise specified by regulatory agencies, AMS
recommends setting the temperature to 40°F when
vending perishable food products. See section 8.9 to
test.
H&S Protection
In the event the temperature exceeds the
NAMA specifications following the recovery period or
during normal operation, an error will be generated
and the vendor will not allow sales. This protects the
consumer from purchasing spoiled food. H&S error
codes are detailed in Section 7.3.
Mixing Potentially Hazardous Food
From the NAMA Construction Standard:
700.1B
In single compartment machines vending
both potentially hazardous and non-potentially
hazardous food, areas not provided with an automatic
shutoff control shall be clearly marked with labels,
lights or other means that will alert the route person
not to stock potentially hazardous food in those areas.
Starting with firmware revision 0.94, all Sensit 3 Food
vendors can be configured for Health & Safety
protection by selection. All vendors shipped from the
factory with FOOD firmware installed will be
configured fir Health & Safety protection of all
selections.
six (6) trays and forty (40) selections for different
products.
*The dash number is dropped for Food, Bottle and
Milk vendors and is replaced with “VCB” or “VCF”.
Serial Numbering System
(Refer to Figure 1.1)
1-0902-0275
If any selections are exempted, it is the operator’s
responsibility to mark those unprotected selections
with the included yellow labels (or other means), and
to instruct route persons on loading restrictions.

FAILURE TO DO SO COULD RESULT IN
AN UNACCEPTABLE HEALTH RISK TO
THE CUSTOMER.
1.3 MODEL IDENTIFICATION
When requesting service, replacement parts
or technical assistance, please copy the information
found on the vendor Serial Plate (Refer to Figure 1.1).
It is attached inside the door near the upper right
corner of the window and is visible from the outside.
The information contained on this plate is necessary
to determine what parts, kits, or maintenance should
be applied to your specific model.
Year
Month
Sequence
On all AMS serial numbers, the first digit identifies
where a merchandiser was manufactured. Those
merchandisers built in the U.S. start with the number
1. Those merchandisers built in Mexico start with the
number 2.
The next two digits identify the year of manufacture.
These numbers are 09 (for 2009) and so forth.
The next two digits identify the month. The first month
of the year is 01 and the last month is 12.
The last four digits identify the number assigned to
each merchandiser during assembly. Numbering
starts with 0000 and continues through 9999,
whereupon these four digits start over.
An example of the numbering system in use is as
follows:
1-0902-1156
This merchandiser was manufactured at the Kearneysville,
W.V. plant in 2009, in February, and was the 1156th
merchandiser manufactured.

The above drawing shows a typical configuration
used in an AMS 35 model vendor.
The top tray in the above example contains
four columns, formed by the placement of dividers,
with motors and large diameter helices in place. Note
that as the 39” vendor is wider, its tray can hold 5
large diameter helices.
The pitch of the helices (the number of slots
for loading product) is given by the number. The size
of the square indicates the size of the helix (small or
large).
All of the top tray helices shown above are of
large diameter, and are of 10, 12 and 15 pitch. The
configuration on this tray can hold 10+12+15+15 = 52
products.
All trays can be configured in this or another
configuration, depending on the products being
vended.
Products which fit in the 10 pitch helix may
be too large to fit in the 15 pitch helix. The product
must be freely pushed out of the column by the helix
to fall into the hopper.
1.
Form a column between dividers, wide
enough for the product. When viewed from
the front of the tray, install a clockwise (CW)
motor and helix on the right side of the
column, and a counter-clockwise (CCW)
motor and helix on the left side of the
column. Note that all normal or standard
motors and helices turn CCW to vend
product. The motors can be any distance
apart. The helices must be of the same pitch.
2.
Using the configuration menu, couple the
two motors together. See Section 6.8.
3.
Install the product into the two helices.
Change the selection and price on the tray.
When this product is selected, the two helices will turn
at the same rate to vend the product.
The bottom tray shown in the above example
contains four columns with small diameter, coupled
helices. The pitch is 7 for all columns, so the
configuration on this tray can hold 7 x 4 = 28
products. Again, the 39” vendor is wider, and its tray
can hold 5 coupled sets.

The fourth tray down as shown in the above
example contains eight columns with small diameter
helices. The pitch is 18 for all columns, so the
configuration on this tray can hold 18 x 8 = 144
products. Note that as the 39” vendor is wider, its tray
can hold 10 small diameter helices.
A working configuration is one column with a
given helix (or two columns coupled,) to vend a given
product. A record of working product configurations,
as shown in the example diagram, will greatly speed
up new set-ups and duplicate vendors.
With Sensit 3, extra wide product can be
vended by ‘coupling’ two motors.

Grounding
Some electrical components have a green or
green/yellow ground wire attached to a grounding
point in the vendor. If it becomes necessary to
remove a ground wire during service, note how the
wire is attached, including the locations of any
washers. After servicing, make sure that the wires
and washers are replaced exactly as they were. Note
that the vendor may appear to work normally without
the ground wires, but there will be a potential shock
hazard from ungrounded components.

3.
Each vendor is designed to operate on a
specific voltage, either single phase 115VAC 60Hz or
220-240VAC 50-60Hz, depending on the country. The
voltage is specified on the serial plate (Refer to
Section 1.3 Model Identification). High voltage areas
include the electrical panel, the refrigeration unit and
fans, and the fluorescent lamp. It is important to

Always test the outlet for proper grounding
before plugging in the vendor.
Always reconnect ground wires after
servicing.
Test the ground fault circuit interrupter
(GFCI) periodically to insure proper
operation. See section 8.11
Fan Contact
Some vendors are equipped with electric
fans, which can start automatically. These fans are
guarded to prevent accidental contact. However,
removal of guards or other components can leave fan
blades exposed and create a physical hazard.
1.
High Voltage Contact
Always test the outlet for proper voltage,
polarity and grounding before plugging in the
vendor.
Always disconnect power to the vendor
before servicing. Allow only fully trained
service technicians to service the vendor if
service must be performed with the power
on.
Always keep electrical connections dry. Do
not place the vendor in or near standing
water.
Never use a worn or damaged power cord.

Always keep hands, hair, loose clothing and
tools away from fan blades.
Never insert hands or tools into concealed
areas.
Always replace protective covers after
service.
4.
Helix Motion and Jamming
Energized vend motors can turn a helix with
considerable torque, creating a possible entrapment
hazard. Also, turning helices may eject tools or other
objects left on trays. A helix that is jammed or caught
can store energy as it binds, which can cause it to
twist or spring outward suddenly even if power is
disconnected. Use gloves and caution when freeing a
jammed helix.

products in helices to avoid jamming.
Always restrain the helix before freeing a
jammed or caught helix.
Always wear hand and eye protection when
servicing the vendor.
Always keep hands, hair, loose clothing and
tools away from moving parts.
Refrigerant Release
The refrigeration system is pressurized and
sealed at the factory. Puncturing or cutting any
component in the system will cause refrigerant gas
and liquid to be propelled out of the system, creating
an immediate physical hazard. Use caution to avoid
accidentally opening the refrigerant system.
It should also be noted that releasing
refrigerant to the atmosphere is a federal crime and is
punishable by law. Any service work requiring the
system to be opened must be performed by a
licensed technician using certified recovery
equipment. Unauthorized service to the sealed
refrigerant system will void the warranty.

AMS SENSIT 3 GLASS FRONT VENDOR
L0118E
3.0 VENDOR SYSTEMS AND COMPONENTS
3.1 SENSIT 3 OPERATION
1.
The Sensit 3 system is comprised of the
primary sensor, the secondary sensor, and
the control logic. The primary and secondary
sensors are attached to opposite ends of the
hopper, and infrared light is passed between
them.
2.
When a selection is made, the vend motor
will begin to run. After several seconds, if no
product falls in the hopper (or motor returns
to home position), the motor will be stopped,
the credit will be maintained and the
customer will be directed to “PLEASE MAKE
ANOTHER SELECTION.”
3.
When the controller measures a variation in
the light intensity during the vend cycle, it
recognizes that a product has fallen through
the light into the hopper. The controller stops
the vend motor (or returns to home position)
and removes the credit.
4.
When the vendor is serviced with the door
open, the protective lens on the sensors can
become fogged up, particularly in hot or
humid locations. In these cases, the vendor
will display “SENSIT BLOCKED – UNABLE
TO VEND” until the fogging has cleared,
usually within a minute after closing the door.
3.2 CONTROL BOARD
The control board controls and monitors the
vendor, DEX, and MDB systems. The control board is
located in the upper left hand corner of the open
vendor door, behind an access door.
Upgrading Software
The software can be upgraded by using a
micro SD card. The card, and card readers, are
available at Office supply chains or on the internet.
Minimum capacity of 512Mb is adequate. See Section
8.1.
Mode Switch
Pressing the mode button (Refer to Figure
3.1) allows the user to get in to the controller’s service
mode to change settings, access vend data, and
check error codes for troubleshooting. Data is
displayed on the front display panel, and entered at
the front selection panel. Pressing the switch again,
closing the door, or waiting approximately 3 minutes
will automatically switch the computer back to vend
mode.
3-1
Figure 3.1 Control Board Components
DEX Jack
The DEX jack (Refer to Figure 3.1) is
provided for use with external features, such as
Speech (Refer to Section 6.10). Data collection with
third party devices can also be made here.
3.3 VEND SENSOR
Primary Sensor
The primary sensor is located on the left of
the hopper when viewing the back of the door. The
sensor, inside a protective housing, sends light to and
receives light from the secondary sensor (both
sensors operate the same way in this regard). It
contains circuitry to send a signal to the control board.
When a product drops through the beam, it causes a
change which is interpreted by the control as a
successful vend. The primary sensor board also
contains circuitry to connect to the secondary sensor,
and to connect the temperature sensor to the control
board. When servicing the primary board, be mindful
of the emitters and detectors These can be damaged
by rough handling.
Secondary Sensor
The secondary sensor, inside a protective
housing, is located on the right side of the hopper
when viewing the back of the door. The sensor also
sends light to and receives light from the primary
sensor. When servicing the secondary board, be
mindful of the emitters and detectors, which can be
damaged by rough handling.
3.4 DOOR
Validator & Debit Card Reader Locations
There are two locations that will accept bill
validators and/or debit card readers. The lower
position meets the guidelines of the Americans with
Disabilities Act (ADA) for access by handicapped
persons (Refer to Section 4.2).
Changer Location
Three screws are installed in the door below
the coin chute. These screws mate to the keyhole
slots on the back of the changer (Refer to Section
4.2).
Coin Box
The coin box is located below the changer,
behind a separate door, and is used to hold overflow
coins when the changer is full. It is removed by tilting
slightly and lifting out.
Door Switch
The door switch is mounted on the back of
the vendor door. The control uses the door switch to
turn off the refrigeration unit when the door is open,
and to switch from service mode to vend mode when
the door is closed.
running in the previous 4 hours. This is a moving
average, and changes throughout the day.
If there are multiple reasons for a chiller to
not be running, the display will show the foremost
reason listed (i.e., door open takes precedence over
low voltage).
Keypad
The keypad is located below the display on
the front of the door. A vending selection is made by
keying in the number combination that corresponds to
the location of an item in the machine. The keypad is
also used to enter data in operation and servicing of
the vendor.
Coin Return Button
The coin return button is located next to the
coin slot. Pressing the coin return button will release
bent or irregular coins that are not accepted by the
changer. If the machine fails to vend a selection that
has been made, pressing the coin return will return
the full credit. If the Force Vend option is disabled, it
can also return the full credit before a selection is
made. If the Bill Changer option is enabled, the coin
return will return change for bills inserted in the bill
validator.
Lighting Options
Several lighting options, depending on the
model and size of the vendor, are available. All
options are intended to illuminate the products
displayed on the trays. Options include single
fluorescent lamps, and single or dual LED lamps (with
adjustable brightness control).
3.5
OPTIONAL REFRIGERATION (CHILLER)
SYSTEM
Display
The display is located on the front of the
door. It serves as the interface for using and
programming the machine. In service mode, it
displays the active function and parameter values. In
vend mode it can display the selection entered, the
price of a selected item and the credit accumulated.
When the machine is idle it can display the time and a
customizable scrolling message.
When the asterisk key (*) is pressed, the
display other machine details. One of the highlighted
characters listed below will be shown in the lower
right corner of the display.
- = Chiller off due to open door
V = Chiller off due to low voltage
D = Chiller off due to defrost timer
P = Chiller off due to pressure timer
H = (Optional) internal heater energized
% = Chiller can run, subject to temperature,
set-point and EnergySENSIT
The number displayed before the % sign
indicates the % of time the compressor has been
Temperature Control
The evaporator fan runs continuously to
circulate air within the cabinet. A temperature sensor
located near the evaporator measures the
temperature of air entering the evaporator. When this
temperature is above the temperature setpoint, the
compressor and condenser fan are turned on.
When the temperature falls to 4°F below the
temperature setting, the compressor and condenser
fan are turned off (Refer to Section 6.6).
Refrigeration Controls
1.
The refrigeration system is operated through
the control board. A temperature sensor in
the cabinet relays the current temperature to
the control.
2.
If the temperature is above the setting that
has been programmed in by the user, the
control sends a 24VDC signal to the
refrigeration relay. The energized relay
closes to complete the high voltage circuit
3-2
AMS SENSIT 3 GLASS FRONT VENDOR
that powers the compressor and the
condenser fan.
3.
If the compressor should overheat, a thermal
overload removes power to the compressor
until it has cooled.
4.
To protect against evaporator freeze-up,
after one hour of continuous running the
compressor will be shut off for 7.5 minutes to
allow for defrosting
5.
When the temperature in the cabinet
reaches 4°F cooler than the temperature
setting, the control de-energizes the relay
breaking the circuit powering the
compressor.
6.
The control will also shut off the compressor
if the door is opened. This is to prevent the
fan from drawing in outside air which may
freeze up.
7.
After the compressor has shut down, the
control will wait until the compressor has
been shut down 3 minutes and if applicable,
the door has been closed 10 seconds before
restarting the compressor. The delay allows
pressure in the system to equalize.
3.6 TRAY RAILS
The rails are located inside the cabinet and
are used to support the trays. The rails are adjustable
up and down in 1” increments (Refer to Section 5.3).
3.7 TRAYS
Refer to section 5, and 11 for optional tray
accessories.
Vend Motors
Two types of motors may be used with this
vendor. The configuration of the machine will be
different if all of one or another is used, or if there is a
mix. S3 software can be used to best advantage if all
motors are designed for homing, but must be similar
within the same tray.
The vend motors are snapped into mounting
holes on the back of each tray. The motor is driven by
24 VDC through a harness from the control board
(Refer to Section 4.2 and Section 5.10).
S3 Vend Motors
The S3 vend motors have a plastic case of
which the rear half is blue. S3 coupled motors can
replace dual helix motors. Where a dual helix motor is
used, replace it with a 23007 motor (having a blue
and ivory case for CCW rotation) and a 23007-01
motor (having a blue and gray case for CW rotation)
and reinstall the helices. Use Tray Setup in Service
Mode to couple the motors in each column together,
causing them to turn at the same rate.
3-3
L0118E
Coupled motors will always stop at the home
position. If one motor runs slightly faster, the slower
will correct itself. Depending on motor configuration,
the motors may jog twice to try to dislodge hanging
product.
Note: When not in Service Mode, and with door
open, press # to reset switched motors to
Home position (Not available for non
switched motors. Refer to Section 6.8).
Motors already at home will not move.
SII Vend Motors
A Sensit II vend motor has a plastic case
which is all ivory in color. A dual helix motor allows
two helices, one for CW and another for CCW
rotation, to be installed. The dual helix housing only
allows helices to be adjacent to each other. These
motors have been discontinued, and are replaced
with S3 vend motors. See section 6.8 when changing
motor types.
Helices
There are four sizes of helices available,
approximately1 ½, 2 5/8”, 3”, and 4” in diameter.
There are several pitches available in each size, and
is determined by counting the number of product
openings in the helix (Refer to Sections 5.6 through
5.10.
Dividers
The dividers separate product columns on
the tray. On snack trays, 2 horizontal slots in the
divider allow for the installation of a candy pusher. To
remove the divider, push rearward and lift. To install,
insert the rear tab in the desired slot, push rearward
and then down. Make sure the locking tabs on the
bottom have engaged their respective slots and pull
forward. Bottle tray dividers are held in place with
screws.
Candy Pusher Bar
The candy pusher bar keeps items pushed
to one side of the column. This is typically used with
tall product. The candy pusher bar is removed by
pulling the bar free from the plastic clips. To reinstall,
it is easiest to squeeze the bar into the clip using
pliers (Refer to Section 5.14).
3.8 ELECTRICAL PANEL
The electrical panel is located in the recess
formed by the right rail mount on the right side of the
cabinet, behind an access panel.
Power Switch
The power switch is located on the side of
the right rail mount near the fuse. The power switch is
used to disconnect 24VAC power to the control board.
The power should be shut off when MDB devices are being
connected or disconnected, when the board is being
serviced, or before any wiring harness is connected to or
disconnected from the control board or sensors.
Fuse Holder
The fuse holder is located on the side of the
right rail mount near the refrigeration unit power
outlet. It contains a 3 amp fast-blow fuse to protect
the 24 VAC power supply to the control board. A
spare fuse is stored in the cover. The fuse holder is
opened by pressing in and down on the indicated side
of the cover and pulling out.
Transformer
The transformer reduces the input voltage to
24 volts AC for the control board. An optional 2nd
transformer supplies power to the window heater.
RFI Filter
The filter removes electrical noise from the
power supplied to the 24VAC transformer to prevent
interference with operation of the control board and
software.
Relay
AMS relays use a 24 VDC signal from the
control board to close the relay and supply power to
the refrigeration unit or other accessories.
Ballast
Power Distribution Harness
The power distribution harness splits the
incoming power into individual leads for the high
voltage components.
Ground Attachment
The vendor electrical ground is made
through the use of grounding studs or screws at the
lower back wall of the right rail mount. Earth ground
and individual ground wires from the high voltage
components are attached here, and should always
be replaced after service or repair.
3.9 POWERED VENTILATION SYSTEM
(OPTIONAL)
On vendors equipped with a powered
ventilation system, a continuously running fan
circulates air through the vendor and exhausts
through the back of the cabinet.
3.10 1.5” HELIX TRAY (OPTIONAL)
The 1.5” Helix Tray is mounted below the
bottom snack tray. To load the tray with small
products such as gum and mints, grasp the tray and
pull forward to unsnap the catches. After loading,
push the tray to the rear until the catches snap in
place.
The motors in the 1.5” Helix Tray operate in the same way
as snack or bottle tray motors (Refer to Section 5.15).
The ballast provides the necessary power to
the optional fluorescent lamp in the door.

4.0 VENDOR PREPARATION AND INSTALLATION
Setting up a vendor has been divided into
three stages. Step 4.1 confirms power and site
suitability. Step 4.2 includes preparations
accomplished in the shop. Step 4.3 is accomplished
on-site, where the vendor is to be located.
4.1 CONFIRMING POWER AT OUTLET
Checking the Outlet (U.S. and Canada)
AMS recommends using a dedicated outlet
which can supply 15 to 20 amps per vendor.
Using a volt meter set to AC VOLTS, check
the voltage between the positive (smaller) lug entry
and the ground lug entry (or center screw on two-lug
outlets). The reading should be between 110 volts
and 130 volts. Next, check the voltage between the
negative (larger) lug entry and the ground. The
reading should be 0 volts. If your results vary, contact
a qualified electrician to correct the outlet wiring
before plugging in the vendor. Abnormal voltage,
reversed polarity or improper grounding may
cause the vendor to malfunction or create
hazardous conditions in the vendor, resulting in
possible injury, damage to the vendor, or fire.
The power cord is shipped in the hopper on
the inside of the door. The cord is supplied with a
standard NEMA 3-wire plug. If there are no 3-wire
outlets available for powering the vendor, a grounding
adapter may be used to convert a 2-wire outlet to
accept the 3-wire plug. The adapter must have a
ground tab or wire which must be fastened to the
center screw of the outlet.
NEVER USE AN EXTENSION CORD
WITH THE VENDOR.
Checking the Outlet (Outside the U.S. and
Canada)
Consult a qualified electrician to check the
outlet for proper polarity, voltage, and grounding.
Check the serial plate on the side of the door to
confirm the vendor is rated for the outlet voltage.
Electrical Service Requirement for CE Compliance
The following requirement applies only to
models using ½ HP compressors and displaying the
CE mark on the serial plate. If this requirement
applies to your vendor, you will find a similarly worded
decal on the back of the vendor near the power cord.

Remove the cardboard spacers and ties
securing the trays.
Make use of Section 5.3 for tray vertical
adjustments and Section 5.4 for tray column
configuration when configuring your vendor
to suit your product.
Make sure the product can slide in and out of
the helix easily. If the product is too snug, it
may cause the helix to jam during vending.
Place it in a helix with a larger opening.
Likewise, if the product is too loose in the
helix, it may not vend properly. Use a helix
with the smallest opening that will allow the
product to slide in and out freely (Refer to
Sections 1.4, and 5.5 through 5.9).
Place tall, narrow products in a column with
a candy pusher bar, which is an adjustable
bar used to push the product to one side of
the column. Typically these are installed in
columns 9 and 0 on the candy trays.
Make sure there is adequate clearance
between the tops of the packages and the
trays above when sliding the trays in and
out, and when the product is being vended.
This is also a good time to set the end
position of the helix to make sure the first
product is held securely in the helix. To do
this, vend a product from each column. The
control stops the helix the instant the sensor
detects a product falling in the hopper. The
end position of the helix will automatically be
set to the correct position when a product is
vended (Refer to 6.7.3 Motor Type to change
motor action).
If desired, the end position can be set
manually by pulling the helix out of the
motor, rotating it, and reinserting it in the
motor.

Initial Power-Up and Cool-down
When placing a refrigerated machine on a
new location it is important to allow the machine to
cool to the operating temperature prior to placing
products in the machine. All food products are to
be pre-packaged. Depending upon the machine’s
initial temperature and ambient conditions, it will take
about 2 to 4 hours to accomplish this. Normal practice
is to place a machine on location and come back the
next day to load it. Do not load warm bottle/milk
and food products into vendor. All bottle/milk and
food products must be pre-chilled.

5.4 TRAY COLUMN POSITIONS
Bottle tray column dividers are fastened in
place and cannot be adjusted. The tray columns used
for snacks, candy and food can be configured by the
user for up to 10 columns wide (for 39” cabinets) or
up to 8 columns wide (for 35” cabinets) for these
trays. Typically the vend columns are set to single
(2.66”) or double (5.32”) width, to be used with the
standard small or large helices, respectively. Single
and double width columns can be configured in any
arrangement on the tray by following the procedure
below.
Plan your tray arrangement before beginning
to determine which extra parts may be required.
Contact your distributor to order the necessary parts.
1.
Disconnect the harness and remove the
tray. Place the tray on a flat, stable work
surface.
6.

9.
Reposition, remove, or add tray dividers
in the desired locations. To remove the
divider, push rearward then lift. Reverse
the procedure to reinstall.
It may be necessary to remove a motor
and helix in order to install some
dividers. Pull forward on the helix to
remove it from the motor. Press down
and rearward on the top motor tab to
remove the motor from the tray.
Reposition the motors to the center of
each vend column, using the upper
mounting position for the large helix and
the lower position for the small helix. It
may be easiest to disconnect the motors
from the harness first.
The harness has 10 sets of motor
connections. The first set of connections
(at the end of the harness farthest away
from the connector) is position 0,
followed by 1, 2, 3, and so on. The last
set (nearest to the wire connector) is
position 8 (35” cabinets) or 10 (39”
cabinets). Starting at the left side of the
tray, attach the harness connectors to
the motors in order. For double
columns, use the even numbered
connection and disregard the odd
numbered connection. (Example: If the
first column on the left is double width,
disregard position 1 and attach the
connectors for position 0). Each set of
connectors has a wide and a narrow
connector, corresponding to a wide and
a narrow tab on the back of the motor.
Place the correct label in front of each
column, according to the motor
connections used.
Reconnect the harness, routing it over
the rail and through the back of the
column.
Reinstall the tray.
After changing the tray configuration, it
will be necessary to reconfigure the
motor matrix (Refer to Section 4.2).
5.5 CHANGING DIVIDERS
1.
2.
To remove, push rearward on the
divider as far as it will go, then lift it up
and out of the tray.
Reverse the removal procedure to

5.6 CHANGING HELICES
Each helix is snapped into an adapter which
snaps into the vend motor.
To remove a helix from the motor, and while
wearing gloves, grasp the helix about one “turn” away
from the motor, and pull straight out sharply. Do not
5-2
AMS SENSIT 3 GLASS FRONT VENDOR
remove the helix adapter if the helix is going to be
reinstalled.
To install a helix, insert the end of the
adapter into the motor, and push the helix back
towards the motor until the adapter snaps into place.

L0118E
After all motor changes have been
made use the Tray Setup option in
Service Mode to configure the motors.
The vendor will not vend from a given
helix when the motor is missing,
jammed or has home switch problems.
After a motor has been configured
check to make sure all the helices are in
the home position. If the end of a helix is
not at its lowest position in the column
pull it out of the motor, turn it until it is,
and reinsert the helix into its motor.
5.8 HELIX EJECTOR
5.11 BOTTLE TIPPER BAR
The ejector’s function is to cause the product
to fall sooner, and therefore stop the helix sooner.
This will help retain the next product in the helix coil,
especially if they are difficult products.
The bottle tipper bar is typically used with
carbonated beverage bottles. The bottles stand
upright. The tipper bar restrains the top of the bottle
so that it falls bottom first, rather than tumbling off the
tray.
1.
The helix ejector is pulled off and
pressed on the helix by hand.
2. The ejector is typically positioned half a
coil, and often much less, from the end
of the helix.
3. The “fin” shaped portion is angled
towards the front of the tray.
The best position and angle for the ejector is
determined by test vending products.
5.9 HELIX ALIGNMENT DEVICE
The helix alignment device is installed under
the bottom left side of the large helices to help keep
them centered in their columns.
1.
2.
To remove, grasp the front of the helix
alignment device with pliers and pull or
pry upward. Take care not to lose the
plastic mounting clips.
Reinstall by pressing the plastic
mounting clips back into the mounting
holes. Note that the mounting flange
goes toward the helix.
1.
2.
To remove, bow the bar until one end
can be pulled free from the support
bracket. Take care not to lose the plastic
bushings in the supports.
To reinstall, reverse the removal
procedure.
5.12 AVOIDING PRODUCT HANG-UPS
Avoid large products, such as chips, from
„hanging-up between the tray and the glass by
loading them „left corner first into the helix. The
bottom left corner of the bag should be in front of the
helix to let the helix push the bottom out first (Refer to
Figure 5.2). An incorrect loading may cause the bag
to fall top first, which could lead to a hang-up. Loading
„left corner first prevents the product from falling top
first.
5.10 MOTOR POSITIONS / HOME
Motor position can be changed sideways for
different width columns, and there are two mounting
positions on the snack tray. The lower and upper
positions are used for the small and large helices,
respectively.

5.13 TALL PRODUCT VENDING
Tray Adjustment and Loading
Place tall, narrow products in a column with
a candy pusher bar. Typically these are installed in
columns 8 and 9 on the candy trays. Rotate the bar
upward or downward to the desired position. It should
hold the product upright, but not pinch or bind the
product.
As delivered from the factory there are two
wide columns for products such as mints, and two
narrow columns for products such as gum.
However, the tray may be reconfigured to fit
the product being vended by adjusting the position of
the column dividers (Refer to Figure 5.4). The
dividers, being adjustable, change the column width.
5.14 CANDY PUSHER BAR INSTALLATION
The candy pusher bar is an adjustable bar
that mounts to any tray divider to keep tall candies
from falling sideways (Refer to Figure 5.3). Four
pusher bars are provided with the standard glass front
vendor.
1.
2.
Snap the pusher bar into the retainer.
Rotate the pusher bar to accommodate
the product.
Adjust the divider position by removing the
screw at the rear of the divider. Pull on the divider
towards the front of the tray to loosen it. Reposition
the divider by inserting the mounting tabs into the
appropriate slots. Push the divider down and to the
rear to tighten it into place. Reinstall the screw at the
rear of the divider.
Test the column for proper vending.

Example: For a price of $1.50, enter 1 5 0.
The user can choose to apply the new price to that
selection (**), all selections on the tray (*1), or all
selections in the vendor (*2). It is usually faster to set
all selections to the most common price in the vendor
(*2), then change individual trays or items that have a
different price.
VALUEVEND
ValueVend starts with the prices that were
set using SET PRICES. Using ValueVend, two
selections are grouped together and offered at a
reduced price. This is possible with any possible pair
of selections in the vendor, including pairing a
selection with itself.
Up to 10 such groups are available. For
example, in one group, soup and crackers are offered
individually at full price, but if one is purchased along

vended using the selection number and price of the
master selection. Entering the selection number of
any linked selection will default to the master
selection number, and the control will vend the next
linked selection in the sequence. If motors are linkedbut not present (or jammed), the next available motor
will run.
From Tray Setup, select 2-Link Motors.
Enter Selection: then select from the
following.
9- EDIT – Use 1 & 2 to select desired link
group. * saves this selection to this link
group.
0- CLEAR – This will unlink the current
selection. The price will revert to its original
value. All other linked selections in that
group will remain unchanged.
* NEXT – Press to increment by one
selection. Any selection number may be
entered directly for faster access.
# EXIT – Returns to the Tray Setup menu.
Repeat for each linked selection.
Motor Type
Motor Type allows the user to change the
motor-stop and credit deduction behavior. See the

available under this function.
Enter tray – enter tray number to change motor type.
Press 1 to change motor type.
Press # to save and exit.
Press 2 to save entire vendor to this

* If S3 motors are used: the switch function is ignored, and homing & coupling are not available.
** "Extra" means that if a drop is not detected by the home position, the motor will move 2 additional
increments to try to vend the product.
*** These are settings for use only with vendors equipped with Sensit II with Homing.
HomeSensor/ will make one full turn and stop at
home position. If a drop was detected, credit will be
accepted. If no drop detected, “Please Make Another
Selection” will scroll allowing the customer to try that
or another selection- or press coin return.
HomeSensor +/ is similar to HomeSensor/, except
that if no drop is detected the motor will make 2 short
jogs in an effort to dislodge the product. If the motor
stops off the home position, the next vend will begin
the process again: stop at home- if a drop is detected
deduct credit. If not, try up to two jogs. This is similar
to the original Sensit sequence, and is the factory
default setting for all vendors.
Home_Only/ disregards the Sensit system, and will
make one complete turn and take credit- whether a
drop is detected or not.
Auto Sensor Recovery is an improvement to the
AMS Sensit system, that allows certain vends even
when the sensor system is blocked or malfunctioning.
If Motor Type is set to Home/Sensor/3 or Home
Sensor+/3, and the sensor system is inoperable, the
control will automatically switch to Home_Only/3 and
allow a vend. Simply put, the sensors will be ignored,
the helix will make a full turn and the credit value will
be deducted. Once the error is cleared, the vendor
will return to its original sensor setting. Note that this
will only work with the 23007 and 23007-01 motors,
and during this temporary mode, selecting an item
with the older style motor will read “selection
unavailable”.
Delayed Stop
The user can program a delayed stop of up
to one second to allow a motor to continue running
after the product has been dispensed. Note: this
feature will only work with the 1-Sensit motor setting.
1.
ENTER SELECTION – Enter the number of
the selection to be delayed, enter 9 to edit,
then enter the time in tenths of a second.
The decimal point is placed automatically.
Example: Entering 8 will program a delay
of 0.8 seconds.
The user can save the programmed delay to
the selection, the entire tray, or all selections in the
6-4
AMS SENSIT 3 GLASS FRONT VENDOR
vendor. Linked selections will use the delay
programmed for the master selection.
Letter / Number
Allows use of either keyboard format. The
control board/software default is for NUMERIC, using
the 12-key keypad. Note that if the control board is
changed this setting may need to be set to “Number”.
This setting should be changed to “Letter” if the
vendor is equipped with 20 pushbutton keypads (with
alphabetic characters). Depending on the setting, the
top tray is designated “1” or “A”, and downward with
numbers (2-8) or letters (B-H).
Configure Motors
Configure Motors moves each switched
motor to the home position (moving the motor only if it
is not at home) in addition to detecting connected
motors.
This selection MUST BE RUN after
changes in the arrangement or number
of motors have been made.
The vendor will not vend from a given helix
when the motor is missing, jammed or has home
switch problems. This requires that Configure Motors
must be run after adding motors or otherwise
changing the motor configuration.
The configuration of connected motors is
stored in memory. If a configured motor is later found
to be missing during a vend, an error message will be
generated in service mode to alert the service person
that the motor is disconnected. (In non-switched
Sensit II firmware, the control allowed new motors to
be auto-configured.)
Coupled Motors
With Sensit 3, configurations to vend extra
wide product can be made by using the coupledmotors feature (Refer to Section 1.5). The coupled
motor feature works by coupling together a set of two
motors. One motor turns counter-clockwise, and the
other motor must turn clockwise. Both motors turn for
the same length of time. Trays may have multiple
coupled motors.
From the Tray Setup menu, press “7”, then enter the
first selection to couple (for example 24).
Press “9” to edit, then enter the column number of the
second column to couple. For this example, press 7 to
couple selections 24 and 27. The second column
could also be 5 or 6 for this set. In this example, the
display will read COUPLE 24,27.
Press the “*” to save these selections and move to the
next selection.
Note that a coupled motor set will vend using the
lowest numbered column selected. In the example
given above, use 24 to select a product. A column
selection of 25 will display the message “PLEASE
MAKE ANOTHER SELECTION”.
6-5
L0118E
If the “*” button is pressed the display will move to the
next selection. Entering the desired number will also
take you to another selection.
Press “0” to clear coupled motor sets from the control
board. The display will read “XX: COUPLE OFF”.
To return to Tray Setup, press the “#” key at any time.
The tray numbers on the front of the tray should be
changed to suit.
The Coupled Motor feature will not
work with Sensit II motors.

Settings
The user can select the following settings.
Force Vend
The factory default is “N” for no. If set to “Y”,
the customer is forced to make a selection before the
control will allow a refund. If the selected product
cannot be dispensed, a full refund can be returned to
the customer. Note that using 6.8.1.3 CHANGE BILL
will override force vend.
No Cheat
The factory default is “Y” for yes. If set to “Y”,
the control will not allow a vend to occur unless
correct change can be returned to the customer. If
disabled, the control will allow the customer to be
short-changed up to $1.00.
Change Bill
The factory default is “N” for no. If set to “Y”,
the customer can insert a bill and receive a full refund
in coins by pressing the coin return button. Note that
using CHANGE BILL will override force vend.
Hold Lost Credit
The factory default is “Y” for yes. If set to “Y”,
any remaining credit after a vend that can t be
returned to the customer will be maintained on the
display for 15 minutes. The customer can add to this
credit to purchase additional items.
Multi-Vend
The factory default is “N” for no. If set to “Y”,
the vendor will hold the change following a vend. The
customer can make additional purchases with the
remaining credit. The customer may push the coin
return button at any time to refund this credit.
Lev2 Coin Mech
The factory default is “N” for no. If set to “Y”,
the vendor will treat the coin mechanism as a level 2
device. Vendor must be powered down before change
will take effect. AMS recommends that this option
remain as “N” for no.
Instant Revaluation
Adds value to card immediately when cash is
inserted.
BILL AND CASH-LESS APPLICATIONS
Sensit 3 software allows running the vendor
with no coin mech.
The changes to allow bill-only and bill and
cashless applications affect fundamental MDB
behavior of the VMC. It was decided to make these
changes without introducing new layers of option
settings. The typical customer using a coin-based
system should not notice any changes except under
unusual conditions. This section will explain those
changes and unusual conditions.
To simplify the discussion, the term “healthy”
will be used to describe a peripheral (coin mech, bill
validator, or a cashless device) which is present,
which is communicating normally to the VMC, and
which has no fatal out-of-service conditions.
MDB OUT-OF-SERVICE
Previously, the VMC would go out-of-service
if what it determined a “critical” peripheral became
unhealthy. In a coin-based system, the coin mech
was the critical peripheral. In a cashless-only system,
the card reader was the critical peripheral. Bill-only
applications were not supported, so an unhealthy
validator was never sufficient to take the machine outof-service.
In this firmware, the machine will only go outof-service if at first at least one peripheral becomes
healthy, then all peripherals become unhealthy.
REMAINING IN SERVICE W/O COIN MECH
If a bill validator is present, and the coin
mech becomes unhealthy, the VMC will now continue
running with the validator (and cashless if present).
Over the past several years, the criteria for an
“unhealthy” finding have become more stringent, as
various reported error conditions such as coin jams
were removed from out-of-service consideration.
Right now, in practical terms, the coin mech either
has to burn out completely or become disconnected
to be considered unhealthy by the VMC s criteria. A
healthy coin mech going unhealthy should be a rather
rare occurrence.
To help notify patrons and service personnel
that the coin mech has become unhealthy, the
EXACT CHANGE message will be activated. This
should discourage patrons from inserting paper
money, unless the prices happen to be in paper
money increments. Also, patrons trying to feed coins
into the mech will notice immediately that the coins
disappear (in the case of a serious coin jam) or fall
through.
unhealthy, the “#” key will be treated as equivalent to
a coin mech escrow return.
BILL-ONLY APPLICATION NOTES:
In a bill-only system, prices must be
restricted to the scaling factor of the bill validator.
Usually, this scaling factor will start from the smallest
paper currency unit instead of the smallest coin unit.
This will limit setting selection prices that would
require change-making.
Due to the absence of a coin mech, the
normal No Cheat logic is disabled, regardless of the
VMC option setting. The VMC s fairness is limited to
not taking in more money than the maximum price in
the machine. As mentioned earlier, the ‘#’ key is
equivalent to escrow return, possibly allowing the
patron to retrieve the last-inserted bill.
The EXACT CHANGE message should
never occur in a pure bill-only system.
BILL PLUS CASHLESS APPLICATION NOTES
Prices will be restricted to the scaling factor
of the cashless device, which is usually the smallest
coin unit.
Revaluation occurs in the same way it does
with a coin mech, except in cases where the payment
medium is at or near its maximum balance. With a
coin mech, the VMC will allow credit to exceed the
maximum balance as long as any excess can be paid
back in coins. Without a coin mech, the VMC rejects
any bills that would exceed the maximum balance (in
a card-first revaluation) or rejects the payment
medium entirely (in a cash-first revaluation).
Hide Card Value Use this feature to display or not
display the value on the card. When enabled, this
will prevent the credit amount from being
displayed during a card swipe. This can avoid
confusion for the customer when the maximum
priced value is displayed before making a
selection for a lesser cost product.
Press “8” to change the YES to a NO and
again to change it back. Press”#” to save any change
and exit this feature.
Card Refund should be enabled only for certain
card readers that have difficulty processing
refunds. Any credit displayed after a failed vend
will be held for 15 minutes. Additional credit may
be added to this un-refundable credit for other
purchases.
Press “9” to change the YES to a NO and again to
change it back. Press”#” to save any change and exit
this feature.
“#” KEY FOR ESCROW RETURN
In bill-only applications, there is no classic
coin return button to request return of the last-inserted
bill. As a result, when the coin mech is considered

Speech
A speech synthesizer option is available for
use with RC Systems Inc. DoubleTalk LT speech
synthesizer. It operates only while the vendor is in
service mode. The speech synthesizer vocalizes
keystrokes and what is shown on the display.
The Options menu selection 5 enters the
synthesizer on/off menu. Press 5 to toggle on/off.
Press # to exit to the Options Menu.
When turned on the synthesizer is inactive
until the vendor is placed into service mode.
The synthesizer must be plugged into the
DEX plug on the control board. A utility cable (AMS
P/N 20786, Harness, Chip Programming) may be
used, but it must be plugged into a male-to-male
gender adapter (Radio Shack 26-231B) followed by a
null modem adapter (Radio Shack 26-264). The serial
cable from the DoubleTalk LT is plugged into the null
modem adapter. The ¼” jack from the utility cable is
then plugged into the DEX plug on the control board
(other DEX functions cannot be used while the
DoubleTalk LT is plugged in). A dedicated cable could
also be constructed.
6.11 SALES BLOCKING

10 recordings, with number 1 being the
most recent.
6.16 EnergySENSIT
The EnergySensit feature is a way of
reducing energy consumption. When enabled,
EnergySensit predicts periods of inactivity and allows
the internal temperature of the vendor to rise slightly,
taking advantage of these inactive times.
Essentially, by looking at past activity, the
vendor learns when to expect vends and when not to
and alters the internal temperature (and hence,
energy consumption) accordingly. Less energy is
used as the internal temperature is allowed to
increase.
Because of this increase in temperature, it's
not recommended for use on temperature-critical
products. Note that the EnergySensit temperature
change feature cannot be enabled while the Health &
Safety function is enabled.
ENABLE
The factory default is "N" for no. When set to "Y,"
EnergySensit is enabled.
NOTE: If the Health and Safety feature is ON, the
display will show “ENERGYSENSIT OFF”
immediately after displaying “HEALTH AND
SAFETY ON.” To use EnergySensit the
Health and Safety feature must be off.
CLEAR HISTORY
EnergySENSIT keeps a history of activity.
The entire contents of the history can be deleted and
a new record will start at that time.
L0118E
PATT TIME
The factory default is 7 days. PATT TIME
(pattern time) is a repeating cycle or time period that
the surrounding environment experiences. Although it
can be set from 1 to 10 days, 7 days represents the
typical cycle of most environments in the US and
many other countries. In a swing-shift type
environment where employees work 4 days and then
have 4 days off, set the PATT TIME to 8.
HIST FACT
The factory default is 3. The HIST FACT
(historical factor) is used to determine how much past
data to use for predicting future periods of inactivity. If
set to 3, it will use data from three pattern times. If set
to 4, it will use data from 4 pattern times, and so on. It
can be set from 3 to 15. The higher the number, the
less likely that someone will purchase a warmer-thanideal product but the energy savings won't be as
great.
DEL TIME
The factory default is 3 hours. DEL TIME
(delay time) is the time it takes the vendible products
to warm (or cool) by the TEMP CHG amount.
Typically, a machine full of beverages will require a
greater delay time than one full of snacks.
LIGHTING
This is an optional feature in energy efficient
vendors. Note that Lighting may be used regardless
of the status of the other EnergySensit features, or of
Health and Safety. The factory default is "N" for No.
Press the “7” key to change between No and Yes.
Lighting uses the historical activity data to
turn the vendor lights off and on for the optional
fluorescent lamps, or to 10% brightness for the
optional LED lamps. If the lights are off (or dimmed),
and the keypad is used or credit activity is detected,
the lights will come on for three minutes.
If the lights are off and the door is opened,
the lights will come on and remain on until the door is
closed. When the door is closed, the lights will turn
off.
Lighting does not affect the vendor 2-line display.
SET TEMP CHG
The factory default is 10° F. TEMP CHG
(temperature change) allows the user to set the
temperature change as an increase from the original
temperature set point (Refer to Section 6.6). During
predicted periods of inactivity, the vendor will maintain
a temperature equal to the temperature set point plus
the temperature change value. This value can be set
from 1°F to 30°F.
For example, 45° chiller set point
+10° EnergySENSIT change
55° vendor temperature
6-9
Note: To add this feature to a standard
vendor, an additional relay and wire harness
are required. Please call the factory Service
Department for more information.
BRIGHTNESS
The optional fluorescent lamp is not
dimmable. It is either on or off.
To use the LED dimming feature the vendor
must be equipped with S3 control board, have a
20158L or later MDB harness, and have single or
dual LED lamps installed.
In Service Mode, scroll to EnergySensit, then
select option 8 for Brightness. Use the keypad 1 and
2 buttons to change the default brightness as shown
on the display. Press the * key to save the new
default setting. The default will operate when the
vendor door is closed. The factory default is 100%.
During the time the door is open the LED
lamps will change to 70% regardless of any settings,
to reduce glare for the operator.
If the EnergySensit lighting feature is turned
on, and the software determines the lights should turn
off, the LED lamps will automatically dim to 10%
(minimum setting). If the keypad is used or credit
activity is detected, the lights will brighten to the
default setting for three minutes.
Brightness does not affect the vendor 2-line display.

7.0 TROUBLESHOOTING
7.1 OUT OF SERVICE MESSAGE
Certain critical errors will disable the vendor.
When this happens, an “OUT OF SERVICE” message
will be displayed. If the error is related to the Health
and Safety function of a perishable food vendor, the
“OUT OF SERVICE” message will be followed by an
error code beginning with “HS.” Refer to the section
on Health and Safety errors below. Please note that
if a Health and Safety error occurs, any food
which may have spoiled should be discarded.
To get the vendor back in service, press the
mode switch on the control board. Any errors will be
displayed immediately. Refer to the list of error codes
and explanations below. Correct the cause of the
error first, then press “0” to clear the error code.
Certain errors will have more detail available: press 1
to see more detailed (sublevel) error codes, or 2 for
date/time of last occurance.
7.2 HEALTH AND SAFETY ERRORS
NAMA specifications for perishable food
vendors require that the temperature in the vendor
must cool to 41°F within 30 minutes of closing the
door (note that Delayed Sales has no effect on this 30
minute cool-down period). This is to allow a recovery
period following loading- however, all products
should be chilled prior to loading. After this
requirement has been met, the temperature in the
vendor must never get above 41°F for more than 15
minutes.
For vendors having this software, the H&S
function is activated automatically when the
temperature is set to 41°F or below. Unless otherwise
specified by regulatory agencies, AMS recommends
setting the temperature to 40°F when vending
perishable food products.
In the event the internal temperature exceeds the
NAMA specifications following the recovery period or
during normal operation, an error will be generated
and the vendor will not allow further sales. This
protects the consumer from purchasing spoiled food.
H&S error codes are detailed in Section 7.3.
The H&S function can be tested by manually
warming the temperature sensor to simulate the
failure conditions (Refer to Section 8.9).

7.4 CLEARING JAMMED MOTOR
If one or more motors and helices become
jammed, the motor(s) will be displayed as a sublevel
error under “Motor Jammed”.
Energized vend motors can turn a helix
with considerable torque, creating a possible
entrapment hazard. Disconnect power to the
vendor or control board before freeing a jammed
helix or motor. Always restrain or block the helix
before freeing a jammed or caught product.
CAUTION: Use caution when freeing jammed
product (Refer to 2.2.4)!

Open the door.
If the vendor has entered an H&S vending
hold, the food products should be disposed
of.
Place a fan on the floor in front of the vendor
to direct room temperature air into the back
of the cabinet.
Do not use any tools or electrical appliances
to chip at, heat up or otherwise „speed up‟
the defrosting action around the coil. Do not
puncture the coil.
Check to see if the base under the
evaporator drain pan is the non-freezing
type, which has two large rectangular vent
holes formed in its longest side. If the base is
made without these large holes contact AMS
to arrange for a Non-Freezing Evaporator
Drain Pan Kit (Refer to Kit Drawing 21351).
Look for the source of excess moisture.
Look for broken or leaking product. Dispose
of it and clean up the liquid.
Inspect the vend hopper and clean it of
liquids and broken containers.
10. Check to make sure the vend hopper door
doesn‟t „hang open‟.
11. Check that the gasket of the chiller housing
is securely contacting the cabinet and is
sealing it on all sides.
12. Check to ensure the sealing putty is firmly in
place around the two openings on the rear,
right hand edge of the chiller housing. Use
more putty if it is missing or is not enough.
13. Check the door gasket around the cabinet
opening. It should be intact.
14. Check to see if the door closes squarely on
all four sides and the lock draws the door
firmly against the gasket.
15. After the evaporator coil has been defrosted,
clean up any water inside the cabinet.
16. Close the door.
17. Plug in the vendor and allow vendor to cool
down before loading perishable products.
8.9 TESTING THE TEMPERATURE SYSTEM
(Health and Safety)
Enter the service mode (Refer to Section
6.0).
2. Press # or * until the Temperature section
appears, then press 2 to view the current set
point. The temperature will be displayed in
both Fahrenheit and Celsius. The setpoint of
the vendor must be 41°F or lower for the
H&S option to be enabled.
3. Press 5 to initiate the NAMA H&S 15 minute
Automatic Shutoff Controls test. At this point
the sensor can either be temporarily
disconnected, causing the controller to
assume a temperature of 125°F/49C, or
relocated outside the cabinet. Relocating the
sensor outside will allow the sensor to be
tested as well.
4. The sensor is mounted to its bracket using
two spring clamps (Refer to Figure 8.3). To
remove it, first unwrap the sensor wire from
the two slots in the bracket, and then slide
the sensor out of the two spring clamps.
5. Relocate the sensor outside the vendor, and
allow to warm up (above 41°). Carefully
close the door. The temperature may be
monitored by pressing the * button. The
sensor bulb has a 20-25 second response
delay to minimize hysteresis error before the
correct temperature is displayed.
15 minutes after the door is closed, the display should
read “OUT OF SERVICE- HS1”. The vendor will not
vend protected products until the door is opened and
the error is cleared (Refer to Section 6.2).
